  1. 11. Quality of Experience on Smartphones : Network, Application, and Energy Perspectives

    Author : Selim Ickin; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QoE; QoS; Energy; Mobile computing;

    Abstract : Smartphones have become crucial enablers for users to exploit online services such as learning, leisure, communicating, and socializing. The user-perceived quality of applications and services is an important factor to consider, in order to achieve lean resource management, to prevent user churn and revenue depletion of service or network providers.

  2. 12. Telecom Networks Virtualization : Overcoming the Latency Challenge

    Author : Dejene Boru Oljira; Anna Brunstrom; Karl-Johan Grinnemo; Javid Taheri; Bengt Ahlgren; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NFV; Telecom networks virtualization; latency; virtualization; cloud computing; network congestion; QoS; Computer Science; Datavetenskap;

    Abstract : Telecom service providers are adopting a Network Functions Virtualization (NFV) based service delivery model, in response to the unprecedented traffic growth and an increasing customers demand for new high-quality network services. In NFV, telecom network functions are virtualized and run on top of commodity servers. READ MORE

  3. 13. Managing Service Levels in Grid Computing Systems : Quota Policy and Computational Market Approaches

    Author : Thomas Sandholm; Lennart Johnsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grid Market; Computational Grid; Service Level Management; QoS; HPC; Grid Middleware; Computer science; Datavetenskap;

    Abstract : We study techniques to enforce and provision differentiated service levels in Computational Grid systems. The Grid offers simplified provisioning of peak-capacity for applications with computational requirements beyond local machines and clusters, by sharing resources across organizational boundaries.

  4. 14. Hybrid ARQ Using Serially Concatenated Block Codes for Real-Time Communication : An Iterative Decoding Approach

    Author : Elisabeth Uhlemann; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Communications; Hybrid ARQ; Iterative Decoding; QoS; Deadline Dependent Coding; Telecommunication theory; Telekommunikationsteori;

    Abstract : The ongoing wireless communication evolution offers improvements for industrial applications where traditional wireline solutions causes prohibitive problems in terms of cost and feasibility. Many of these new wireless applications are packet oriented and time-critical. READ MORE

  5. 15. Hybrid Routing in Next Generation IP Networks : QoS Routing Mechanisms and Network Control Strategies

    Author : Antoine B Bagula; Björn Pehrson; Bukhard Stiller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teletraffic systems; Teletrafiksystem;

    Abstract : Communication networks have evolved from circuit-switched and hop-by-hop routed systems into hybrid data/optical networks using the Internet as a common backbone carrying narrow- and broad-band traffic offered by a multitude of access networks. This data/optical backbone is built around a multi-technology/multi-protocol routing architecture which runs the IP protocols in a collapsed IP stack where ATM and SONET/SDH have been replaced by the suite of Generalized Multiprotocol Label Switching (GMPLS) protocols.
